IT WAS the date Maria Antoinette was guillotined in 1793 and when the Houses of Parliament burned down in 1834.

So perhaps it is only fitting David Cameron will meet his fate on Thursday, October 16.

The Sunday Express has calculated this is the date the PM will have to apologise personally to the Queen for his recent indiscretions.

Their weekly audiences take place only when Parliament is sitting and usually on a Thursday.

MPs return to Westminster on Monday, October 13. Last month he had to admit he was “extremely sorry and very embarrassed” after he was overheard telling ex-New York mayor Michael Bloomberg the Queen “purred” with delight on hearing Scotland voted “no” in the referendum.

Royal protocol demands private conversations with the Queen are not discussed. He vowed to apologise to her in person, adding: “I am not going to discuss my conversations with the Palace ever again.”

However, he made a second royal gaffe last week, when he told MPs the Queen was corrected for mistakenly claiming to have the original of an Anthony van Dyck painting hanging in his country residence, Chequers.
